The idea of an empire, a large swath of territory, diversely peopled and ruled by the iron will of a single dictator, was birthed by the Akkadians. Akkad, as an empire was founded by one ambitious and somewhat conniving Sumerian by the name of Sargon.
In the early days, Mesopotamia was a collection of city-states all ruled by their own king. The goal of each city-state (apart from trying to defend themselves against their enemies) was to try and subdue their neighbors thereby creating a single unified country or empire.
According to historical legend, Sargon was raised in the palace of the Sumerian king Kish. He was a foundling, an orphan abandoned and retrieved by a minor servant in the palace. Sargon worked his way up the ranks to become cupbearer to the king.
Using his position and the trust placed in him by the king, Sargon began to slowly gain popularity among powerful courtiers and the military alike. Using his influence over the military Sargon encouraged a coup. Under Sargon’s direction, the military assassinated king Kish and made Sargon ruler in his place.
But a single kingdom wasn’t enough for Sargon. Hungry for power he set his sights on the entire fertile crescent. Fighting over 50 wars in his attempt to conquer the neighboring cities in the fertile crescent, Sargon prevailed. He named his newly minted empire Akkad and the age of empires was born.
